B R U S H SE'ECIFIGATION forming part of Letters Patent No. 684,549,dated October 15, 1901.

Application filed January 16, 1901. Serial No. 43,529. (No model.)

To aZZ whom it may concern:

Be it known that I, JAMEs MCDERMOTT, a citizen of the United States, anda resident of the city of New York, in the county of New York and Stateof New York, have invented certain new and useful Improvements inBrushes, of which the following is a specification.

My invention relates to new and useful improvements in brushes used instreet-cleaning and similar purposes, and has for its object a brushespecially adapted for the work to be performed in the qualities ofstrength, durability, and reliability in use.

A further object is to provide a brush in which the parts subject to themost severe wear may be readily renewed.

Brushes used for street and stable cleaning and for similar purposesmust of necessity be coarse and subject to rough usage. The striking ofthe ends of the stiff bristles has a tendency to drive them through thebrush-back, and to prevent this the holes in the block are boredentirely through the block, and thus the block supports the bristlesthroughout its entire thickness and renders the wiring of the bristleseasy of accomplishinent. To protect and conceal the wiring, I provide ametallic casing so formed as to be conveniently secured to thebrush-block, and one which will prevent the brush-block from warping orsplitting from moisture or severe use.

In the drawings illustrating my invention, Figure 1 is "a perspective ofa brush constructed in accordance with my invention. Fig. 2 is a detailsectional perspective view of a portion of the brush-back and casing,showing clearly the manner in which the block is bored and the bristleswired. Fig. 3 is a plan view of a metallic blank from which the casingmay be formed. Fig. 4- is a similar view of the casing thus formed. Fig.5 is a plan view of the bottom of the casing with the brush-blocktherein and the scraper thereon. Fig. 6 is a plan view of the block.Fig. 7 is a longitudinal section of same. Fig. 8 is a plan of scraper.Fig. 9 is a detail View of scraper with securing-bracket attached. Fig.10 is a section of a slightly modified form in which the casing may bemade 3 and Fig. 11 is a detail perspective view of a n1odification,showing manner in which the handle may be attached to the casing.

Referring to the drawings, the numeral 1 indicates the metallic casing,the same being preferably made from a blank 2, out so as to be bent upondotted lines 3, making the ends 4, and, bending upon the lines 3, formsthe sides 5 of the casing. Finally, the ends a are bent around upon theends 4:, and rivets 6, through the parts a and at, complete the casing.The casing thus formed is adapted to receive the block 7, in whichIprovide holes 8, bored, preferably,thesamediameterentirelythrough theblock. The holes in the ends of the block are bored at an angle, so asto protect the points of the end bristles, and this same inclination isgiven the holes adjacent to the sides of the block. In ablock thus boredthe bristles 9 are inserted as shown in Fig. 2, and are wired in theusual manner, the bristles having the advantage of the support of theentire thickness of the block and the Wiring being greatly facilitatedby the large size of the holes. The block. is made to fit snugly thecasing and is secured therein, preferably, by screws 10, or it may bedone by means of bolts passing through the block, as at 11.

The casing forms a substantial foundation for the attachment of ascraper 12, a foundation that takes the strain of use of the scraperentirely from the brush-block. The scraper 12, Fig. 9, is of the usualform of blade, ex cept the flanges integral with the blade by which itis fastened to the brush-block are omitted. Brackets 13, that may be ofbar metal and twisted into shape or of malleable or steel castings, areriveted to the ends of the casing, as shown, and the scraper is rivetedto these brackets, as in Fig. 5, and a central bracket 14 may be addedto stiifen the scraper. The ends of the scraper are often employed todig and clean out corners and crevices and must be of suiiicientstrength for this purpose.

Holes 15 are provided in both the casing and brush-block to receive thehandle 16. As it is sometimes desirable to reverse the handle, so thatthe scraper may be used in the manner of a hoe, an additional hole 17,Fig. 1, may be provided. 7

It may be desirable in some cases to form the casing so that thebrush-block may be pressed into it, thus making a more secure fastening,and in such cases the casing would be given more or less flaring sides,as illustrated in Fig. 10.

The strain of the handle upon a wooden brush-block is considerable, andto distribute this strain a bifurcated handle may be employed in themanner shown in Fig. 11, the handle 16 terminating in prongs 18 18'. Theaddition to the handle of a brace 19 further distributes the strain anddivides it between the brush-block and the casing.

Just the position the bristles will be held in in the holes in thebrush-block by the wires and the top plate of the casing will be seen inFig. 2.

The brush made in accordance with my invention and illustrated in Fig. 1embodying the improvements herein set forth in their combination make abrush not only efficient, stronger, and durable, but introduce theeconomical feature of the renewals of the brushplate and effect areduction of the cost of the brush in any service in which it may berequired.

Having thus fully described my invention, what 1 claim is- 1. In a brushthe combination with a brushblock having bristle holes made entirelythrough the block, said holes having straight side walls so that thebristles are supported for the entire thickness of the block, of ametallic casing or backing having side and end flanges fitting over thesides and ends of the brush block and having projections bent around thecorners of said brush-block, substantially as specified.

fitting over the sides and ends of the brushblock, and having projectingend pieces bent around the corners of said brush-block, and end bracketssecured to the projections a and the ends of the casing, and ascraper-blade secured thereto.

4. As an article of manufacture, a brushblock having bristle-holes madeentirely there-- through, said holes having straight side walls so thatthe bristles are supported for the entire thickness of the block, ametallic backing or casing having side and end flanges fit= ting overthe sides and ends of the brush= block and having projections bentaround the corners of said brush-block, and brackets secured to saidprojections and ends of the casing and having a scraper-blade securedthereto.

Signed at New York, in the county of New York and State of New York,this 8th day of January, A. D. 1901.
